PIN CARRIAGE INPU-T ARRANGEMENT Filed Dec. 30, 1964 WI 22 l UnitedStates Patent O Forest, Germany Filed Dec. 30, 1964, Ser. No. 422,352

Claims priority, application Germany, Jan. 7, 1964, K 46.742 Claims.(Cl. 23S- 60) The present invention relates to an input arrangement forthe pin carriage of an accounting machine or lcalculator of the ten keytype, and more particularly to an input arrangement in whichelectromagnetic means control the actuators by which the pins of the pincarriage are set to represent digits, and by which control pins areshifted on the pin carriage to cause stepwise movement of the same tosuccessive ordinal positions.

In some constructions according to the prior art, the digit representingpins and the control pins are individually operated by a correspondingseries of electromagnetic means. However, this has the disadvantage thateach electromagnetic means must have suicient power to actuate and shifta pin on the pin carriage. Electromagnetic means capable of performingthis task are comparatively large and difficult to build into thelimited space available in a business machine. y

In accordance with an improved construction of'the prior art as shown inthe British Patent No, 950,242, selector magnets are respectivelyassociated with the digital pins of each order, and operate a couplingmeans which connects the actuators of the pins with an electromagneticoperating means so that the force for setting any of the pins is notsupplied by the selector magnets, but by a single electromagneticoperating means which is constructed to have sufficient power for thispurpose. In such an arrangement, the selector magnets can be small andtake up little space so that a great deal ot space is saved comparedwith older constructions, even though an additional electromagneticoperating means of greater power has to be added.

The electromagnetic operating means moves a bar which is coupled by thecoupling members of energized selector magnets to the actuators by whichthe digital pins are set. The bar of the electromagnetic -operatingmeans directly acts on the control pins so that the pin carria-ge movesone step when a digital value has been entered by actuation of a digitalpin.

However, there is no assurance that a digital pin was actually set and acorresponding vaue entered in this manner int-o the pin carriage. Forexample, if a selector magnet fails to actuate its coupling member, theelectromagnetic operating means will actuate the respective control pinand cause the pin carriage to make one step although the coupling memberof the electromagnetic means of the respective digit value was not inthe coupling position. In other words, instead of the intended digit,the digit zero is stored in the respective order of the pin carriage a1-thou-gh the operator has no way of knowing that this happened.

It is one object of the invention to overcome this disadvantage of knownpin carriage input arrangements, and

Patented May 2, 1967 ICC to assure that the pin carriage is moved to thenext following ordinal position only if a digital value was introducedlinto the same.

Another object of the invention is to assure that the control pins of apin carriage which cause the stepwise movement of the carriage areoperated depending on the actuation of the digital pin.

Another object of the invention is an input arrangement for a pincarriage in which the actuators by which the digital pins are set,control the actuator for the control pins by which the pin carriage iscaused to move to the next following ordinal position.

Another object of the invention is to provide a pin carriage arrangementin which a series of selector magnets are associated with the digitalpins, and with the control pins and actuate coupling means by which anelectromagnetic operating means is coupled to actuating means fordigital pins which also cause the actuation of the corresponding controlpins.

Another object ofthe invention is to provide in an input arrangementwhich is controlled by electromagnetic means, manually operated meanswhich control the actuation of the digital pins while the movement ofthepin carriage takes place under the control of the actuators of thedigital pins.

With these objects in view, the present invention relates to an inputarrangement for the pin carriage of an accounting machine or calculator.One embodiment of the invention comprises pin carriage means including amovable carriage, a group of pins mounted on the carriage and includinga series of digital pins and a control pin; an actuating member operablefor actuating the control pin; a plurality of digital actuating meansindividually operable for actuating the digital pins and for operatingthe actuating member; and operating means for selectively operating thedigital actuating means.

Whenever a selected digital actuating means is operated, it actuates adigital pin to represent a digital value, and at the same time itoperates the actuating member so that the control pin is actuated tocause movement of the carriage to the next `following ordinal position.i

Since the control pin is not actuated by the operating means, but isactuated by the digital actuating means, the pin carriage cannot performa step unless a digital pin has been actuated and set.

In the preferred embodiment of the invention, a single electromagneticoperating means, and a plurality of electromagnetic selector means areprovided. The selector means, when enengized, move coupling means to acoupling position in which the electromagnetic operating means iscoupled with one of the digital actuating means to cause actuation of adigital pin. The actuating member of the control pin is operated by thedigital actuating means only when a selector means has moved a couplingmeans to the coupling position so that it is assured that a control pincannot be actuated unless a digital pin has been actuated.

In the preferred embodiment of the invention, the nonactuation of adigital pin represents the digit zero, so that a coupling means and anelectromagnetic selector means is also provided for the actuating memberand used when the digit zero is to be represented. Actuation of thecontrol pin by the actuating member coupled to the electromagneticoperating means causes the pin carriage to move one step without theentry of a digit by the digital actuating means which are associatedwith the digits from 1 to 9.

Unless the digit zero is to be entered into the pin carriage, it is notpossible that the pin carriage moves to the next following ordinalposition without the entry of one of the digits from 1 to 9, even if thecorresponding selector magnet fails. In this event, no digital valuefrom 1 to 9 is entered, and the actuating member of the control pin isnot operated and consequently the pin carriage remains in the ordinalposition, indicating to the operator that a malfunction has occurred.

The novel 'features -which are considered as characteristic for theinvention are set forth in particular in the appended claims. Theinvention itself, however, both as to its construction and its method ofoperation, together with `additional objects and advantages thereof,will be best understood from the following description of specicembodiments when read in connection with the accompanying drawings, inwhich:

FIG. 1 is a perspective view illustrating the embodiment of theinvention;

FIG. 2 is a fragmentary perspective view illustrating a rst operationalposition of the apparatus shown in FIG. l; and

FIG. 3 is -a fragmentary perspective View illustrating anotheroperational position of the apparat-us.

Referring now to the dra-wing, a pin carriage 1 is mounted on a pair ofguide rails 2 and 3 for movement along the same. A spring 4 is securedby a hook to pin carriage 1 and urges the same to move in the directionof the arrow A. Digital pins 5 respectively representing the digits from1 to 9 are arranged in parallel rows which extend transverse to thedirection of movement of the pin carriage, each transverse row beingassociated with a decimal order. A control pin 6 is correlated with eachordinal row of digital pins 5, and aligned with the same.

The input carriage means 1, 5, 6 is operated in a conventional manner tostore digital values by depressing a digital pin 5 of each row to anactuated position. Whenever a pin 5 is actuated in an ordinal row, thecorresponding pin 6 must also be depressed and actuated to causemovement of the pin carriage in the direction of the -arrow A to thenext following position thereof in which a digital pin is depressed andactuated in the next following ordinal row together with thecorresponding control pin v6. When the digit values of the severalorders of a number have been entered into the parallel rows of digitalpins, the actuated digital pins are sensed by differential elements, notshown, in a conventional manner to transfer the number into a storageregister, as is well known to those skilled in the art.

Whenever a control pin 6 is depressed and actuated, the stop 7 is nolonger effective to hold the pin carriage against the action of spring4, and the pin carriage moves one step to the next following position in`which the control pin 6 of the next following order abuts stop 7. Nodigital pin 5 is provided for the digit zero, since nonactuation of thedigital pin of the respective ordinalrow, `and actuation of therespective contr-l pin `6 represents the digit zero. In other words,when the pin carriage 1 makes a step upon actuation of a control pin 6lwhile no digital value is entered, the corresponding position of thepin carriage represents the digit Zero.

A shaft 8 is mounted in the frame of the machine and supports a digitalseries of actuating lever means, of which only the lever means 9 and 10are shown. An actuating lever means is provided for each of the digitalpins 5, that is for the digits from l to 9, most of the digitalactuating means being omitted in FIG. 1 for the sake of clarity. The twoIactuating lever means 9 and 10 have downwardly projecting pointedactuating portions 12 and 13 respectively resting on the tops ofcorresponding digital pins, and it will be understood that all digitalpins of a CTL row are engaged in the same manner and that pivotalmovement of an actuating lever means will cause movement of thecorresponding engaged digital pin 5 to a lower -actuated position. FIG.1 shows the actuating lever means cooperating -with the first row ofdigital pins 5, and after a value have been entered in the rst row ofdigital pins, the carriage performs one step in the direction of thearrow A, and the actuating portions 12 and 13 of the actuating levermeans will then cooperate with the digital pins 5 of the second row.Some of the actuating lever means are straight double-armed levers, asshown for actuating lever means 9, while other actuating lever means areconstructed as shown for actuating lever means 10, and have one armending in actuating portion 13, a bridge portion extending parallel toshaft 8, and a second double-armed lever 10 also mounted for turningmovement on shaft 8. Lever arm 10 has a projecting stud or roller 16,Iand actuati-ng lever means 9 has an arm at whose end a correspondingstud or roller 15 is mounted. Studs 15 and 16, and corresponding studson the other digital actuating lever means, which are not shown in thedrawing, cooperate with coupling means in the form of arms, of which-only coupling means 18 and 20 are shown in FIG. 1. Coupling `arms 18and 20 have thinner coupling portions 18 and 20 respectively cooperatingwith studs 15 and 16 in a manner which will be described hereinafter ingreater detail. A coupling means is provided for each of the digits fromyone to zero, and since the coupling means have to be spaced a certaindistance from each other, it is necessary to provide some of theactuating lever means, for example lever means 10 with a second lever 10which is positioned to cooperate with the respective coupling arm 20,20.

An actuating lever member 11 which is correlated with control pins 6, isalso mounted on shaft 8 for turning movement. A control rod 28 issecured to actuating lever member 11 and is connected at the endsthereof to a pair of arms 29 which are turnable about shaft 8, only-onearm 29 being shown in the drawing for the sake of clarity.

Control rod 28 extends across all digital actuating lever means, asshown for lever means 9 and 10 and constitutes a connectiong means forconnecting the same with actuating members 11, 28, 29. A spring 36 issecured to the actuating members 11, 28, 29 and to a stationary rod 36awhich is -secured to the frame of the machine, so that the actuatinglever member 11 is urged to turn in counterclockwise direction until itsstop portion 38 abuts a stop bar 37. Actuating lever member 11 has anactuating portion 14 which projects downwardly and is located directlyabove a control pin 6 in the position illustrated in FIG. 1. Whenactuating lever member 11 is turned in clockwise direction, therespective control pin 6 is depressed and actuated, permitting carriage1 to move one step in the direction of the arrow until stop 7 engagesthe next following pin.

Corresponding springs 36 are attached to all digital actuating levermeans, as shown for lever means 9 and 10 and urge the same to turn incounterclockwise direction until abutting stop portions 39 of manuallyoperable key levers 40, of which only one is shown in FIG. 1.

Actuating lever member 11 has a stud 17 cooperating with a couplingportion 19 of a coupling arm 19.

Coupling arm 19 cooperates with a movable armature 21 of Aanelectromagnetic selector means 23. Nine additional electromagneticselector means, of which only selector means 24 and 25 are shown, areprovided with corresponding armatures 22 which respectively cooperatewith nine coupling means for the digital actuating means, of which onlythe coupling means 18 and 19 are illustrated.

Springs 26 act on each of the armatures 21, 22 of the electromagneticselector means 23, 24, 25 and so forth to retract the respectivecoupling means to a position spaced from the corresponding studs 16, 16,17.

It will be understood that an armature 22 is also connected to couplingmeans 18, but not shown in the drawing. Ten electromagnetic selectormeans, ten armatures, and ten coupling means are provided of which nineare correlated with the nine digits and with the nine digital actuatingmeans, whereas the tenth is correlated with the actuating lever member11 and with the control pins 6 which are used to represent the digitzero. Keys 40, of which only one is shown, may be used for a manualselection and act directly on actuating levers 12, 13. During normaloperations, selector means 23, 24, etc., are energized by electricimpulses from the storage means of an accounting machine, for example,while the keys are not used.

When the electromagnetic selector means are not energized, the couplingmeans are pulled by springs 26 to a position resting on Ia bar 27 whichextends across all coupling means.

An electromagnetic operating means 33 has a mov able armature 32connected to an arm 31 which is mounted on shaft 8 for turning movement,and is secured to an operating member 30 in the form of a transverselycurved bar. Operating member 30 extends across .all coupling means 18,19, 20, and more particularly across the coupling portions 18', 19',20'. A spring 34, shown in FIG. 2 urges arm 31 to turn with operatingmember 30 to a position in which the edge 30 of operating member 30 isspaced .from the studs of the digital actuating lever means and of theactuating member 11.

The distance between the edge 30' and the studs, for example studs 15,16 and 17, is great enough to permit advance of the coupling means, forexample coupling arms 18, 19 and 20 to coupling Ipositions in whichcoupling portions 18', 19', 20 are located between the edge 30" and therespective stud.

FIGS. l and 2 illustrate a normal position of the rest of the apparatus.The digital .actuating lever means, for example 9 and 10, and actuatinglever member 11 are held by springs 36 in a normal position in which theactuating portions thereof, for example portions 12, 13 and 14 arelocated above the corresponding pins 5 and 6 of the rst row of pins. Asshown in FIG. 2, the coupling arm is retracted from the edge 30 ofoperating member 30, and from the corresponding stud 16 of the digitalactu-ating lever means 10. Spring 3-4 turns arm 31 in clockwisedirection as viewed in FIG. 2 to a position abutting a stop 35 so thatthe edge 30' is spaced a distance corresponding to the height of thecoupling portion 20 from the corresponding stud 16, and the sameposition is assumed by all other coupling arms and studs.

In the position of FIG. 3, the electromagnetic selector means 23, whichis associated with the digit zero and with actuating lever member 11, isenergized and has attracted armature 21 to move coupling arm 19 to acoupling position in which coupling portion 19 is located between stud17 of actuating lever member 11 and edge 30 of operating member 30.

As is well known to those skilled in the art, the electromagnticoperating means 33 is energized after energization of an electromagneticselector means such as 23, 24, 25, energization of which determines theselection of the digit to be entered.

When electromagnetic operating means 33 is energized, its armature 32 isattracted, and turns arm 31 so that operating member 30 is raised anddisplaces coupling portion 19 so that stud 17 is raised and actuatinglever member 11 is turned about shaft 8 in clockwise direction as viewedin FIG. l to depress and actuate the respective control pin 6 permittingthe carriage 1 to make one step. Since none of the digital pins 5 in therespective lirst row was depressed and actuated, none of the digits fromone to nine is entered into the register during the following sensing ofthe position of the pins of the pin carriage, and the value zero isentered into the register.

Assuming that one of the electromagnetic selector means, which representthe digits from one to nine, iS energized, for example electromagneticselector means 25, armature 22 will be displaced and coupling arm 20shifted until coupling portion 20 is located between operating member 30and corresponding stud 16 of the digital actuating lever means 10, 10.In this event, the electromagnetic selector means 23 associated with thedigit zero is not energized, and consequently the .actuating levermember 11 is not coupled by coupling arm 19, 19 to the operating member30.

Upon energization of electromagnetic operating means 33, operatingmember 30 is raised and displaces stud 16 by means of coupling portion20' whereby digital actuating lever means 10, 10' is turned in clockwisedirection as viewed in FIG. 1 so that actuating portion 13 depresses oneof the digital pins 5 and places the same in an actuated position whichcan be sensed after entries have been made in ordinal rows of pins ofthe pin carriage in accordance with the number of orders of the enterednumber.

It is, however, necessary that the control pin 6 of -the respective rowof pins is also depressed and actuated, since otherwise the carriagewould not perform a step to associate the next following row of pinswith the digital actuating means and with the actuating member 11.

Since the rod 28 is engaged by any one of the digital actuating levermeans when the same moves to actuate a digital pin 5, movement ofactuating lever means 10 will cause depression of rod 28 against theaction of spring 36 so that actuating lever member 11 will be turned byrod 28 in clockwise direction as viewed in FIG. l although its couplingmeans 19, 19 is not in the coupling position. Turning of actuating levermember 11 effects depression and actuation of control pin 6 by theactuating portion 14 so that the pin carriage can move one step to thenext following ordinal position. It will be seen -that the control pin 6can only be act-uated if either the digit zero is to be entered in theregister, or when one of the digital actuating means has actuallyentered a digital value by actuating a digi- -tal pin 5. In the eventthat one of the electromagnetic selector means 24, 25, etc. fails tooperate, the value zero will not he entered into the register which isthe case in the construction according to the prior art. Unless one ofthe digital actuating lever means moves and actuates actuating member 11by connecting means 28 to depress a digital pin, the correspondingcontrol pin will not be actuated, and consequently the pin carriage willremain in the same position and perform no step which will indicate thatno digital value has been entered into the pin carriage. In theconstructions of the prior art, operation of the electromagneticoperating means 33 caused actuation of the respective control pin 6 andmovement of the carriage, even if due to failure of the electromagneticselector means no digit vwas actually entered into the pin carriage bydisplacement and actuation of a digital pin.

When the electric impulses energizing electromagnetic operating means 33and the electromagnetic selector means 23, 24, 25, etc., are terminated,springs 36, 34 and 26 return all movable parts of the device to thenormal position of rest.

It is also possible to enter digital values by operation of key levers40 which directly act on the digital actuating lever means, as shown forlever means 9 and 10. When one of the digital actuating lever means isturned, rod 28 is displaced, as described above, and actuating levermember 11 is turned about shaft 8 to depress and actuate control pin 6so that the pin carriage performs one step to the next ordinal position.The selector means 23, 24, 25 and the associated coupling means are notactuated during a manual selection. Un-

less a digital actuating lever means has actually moved down andoperated a digital pin, control pin 6 will not be actuated, and pincarriage 1 will not move. Arm 39 of each key lever 40` is raised by thecorresponding digital actuating lever means under the action of therespective spring 36 until arm 39 abuts the lower edge of stop bar 37.

It will be understood that each of the elements described above, or twoor more together, may also find a useful application in other types ofinput arrangements for the pin carriage of a calculator or accountingmachine differing from the types described above.

While the invention has been illustrated and described as embodied in apin carriage input arrangement preventing movement of the pin carriagewithout entry of a digital value, it is not intended to be limited tothe details shown, since various modifications and structural changesmay be made without departing in any way from the spirit of the presentinvention.

Without further analysis, the foregoing will so fully reveal the gist ofthe present invention that others can by applying current knowledgereadily adapt it for various applications without omitting featuresthat, from the standpoint of prior art, fairly constitute essentialcharacteristics of the generic or specific aspects of this inventionand, therefore, such adaptations should and are intended to becomprehended within the meaning and range of equivalence of thefollowing claims.
